  Comparison of Facially Amphiphilic Biaryl Dendrimers with Classical Amphiphilic Ones Using Protein Surface Recognition as the Tool

  摘要：

  Facially amphiphilic biaryl dendrimers are compared with the more classical benzyl ether amphiphilic dendrimers for molecular recognition, using protein binding as the probe. The protein used for the proposed study is chymotrypsin (ChT). A generation-dependent binding affinity was observed with the benzyl ether dendrimers, while the affinities were independent of generation in the case of the biaryl dendrimers. Similarly, although the ligands incorporated in both dendrons are the same, the biaryl dendrimers are able to bind more proteins compared to the benzyl ether dendrimers. For example, G3-dendron of biaryl dendrimer can bind six molecules of chymotrypsin, whereas G3-analogue of benzyl ether dendrimers can bind only three molecules of chymotrypsin. This result is consistent with our hypothesis that the internal layers of the facially amphiphilic biaryl dendrons are solvent-exposed and accessible for recognition. In addition, the systematic size differences in dendrons were also used to gain insights into the substrate selectivity that the enzyme gains upon binding to a ligand scaffold.

  日期：2018.5.18

  A practical method for the nucleophilic substitution (SN) of alcohols furnishing alkyl chlorides, bromides, and iodides under stereochemical inversion in high catalytic efficacy is introduced. The fusion of diethylcyclopropenone as a simple Lewis base organocatalyst and benzoyl chloride as a reagent allows notable turnover numbers up to 100. Moreover, the use of plain acetyl chloride as a stoichiometric

  介绍了一种在立体化学转化下以高催化效率对提供烷基氯化物，溴化物和碘化物的醇进行亲核取代（S N）的实用方法。二乙基环丙烯酮作为一种简单的路易斯碱有机催化剂与苯甲酰氯作为一种试剂的融合，可实现高达100的显着营业额。此外，首次证明了在转化型S N型转化中使用纯乙酰氯作为化学计量的促进剂。。操作上简单明了的协议展现出高水平的立体声选择性和可伸缩性，并且可以容忍各种功能组。

  and waste‐balance (E‐factor down to 2). Chiral substrates are converted with excellent levels of stereochemical inversion (99 %→≥95 % ee). In a practical one‐pot procedure, the primary formed chlorides can be further transformed into amines, azides, ethers, sulfides, and nitriles. The value of the method was demonstrated in straightforward syntheses of the drugs rac‐Clopidogrel and S‐Fendiline.

  简单的甲酰胺催化剂可促进以苯甲酰氯为唯一试剂将醇类有效转化为烷基氯。这些亲核取代是通过亚胺基活化的醇作为中间体进行的。这种新颖的方法甚至可以在无溶剂条件下进行，其特点是具有出色的官能团耐受性，可扩展性（> 100 g）和废物平衡（电子因子低至2）。手性底物的转化具有优异的立体化学转化水平（99％→≥95％ee）。在实际的一锅法中，初步形成的氯化物可以进一步转化为胺，叠氮化物，醚，硫化物和腈。该方法的价值在药物rac ‐ Clopidogrel和S‐芬迪林。

  A general formamide‐catalyzed protocol for the efficient transformation of alcohols into alkyl chlorides, which is promoted by substoichiometric amounts (down to 34 mol %) of inexpensive trichlorotriazine (TCT), is introduced. This is the first example of a TCT‐mediated dihydroxychlorination of an OH‐containing substrate (e.g., alcohols and carboxylic acids) in which all three chlorine atoms of TCT

  介绍了一种一般的甲酰胺催化方案，用于将醇有效转化为烷基氯，这是通过亚化学计量的量（低至34 mol％）的廉价三氯三嗪（TCT）促进的。这是TCT介导的含OH底物（例如，醇和羧酸）的二羟基氯化的第一个例子，其中TCT的所有三个氯原子都转移到了起始原料中。因此，增强的原子经济性可显着改善废物平衡（电子因子低至4），成本效率和可扩展性（> 50 g）。此外，当前的程序以高水平的官能团相容性和立体选择性为特色，因为仅释放弱酸性氰尿酸作为排他性副产物。最后，一锅法制备胺N 2反演，证明了所提出方法的高实用价值。

  thermodynamic driving force and lower kinetic barriers. However, the cheapest acid chloride phosgene (COCl2) is a highly toxic gas. Against this background, phenyl chloroformate (PCF) was discovered as inherently safer phosgene substitute for the SN‐type formation of C−Cl and C−Br bonds using alcohols. Thereby, application of the Lewis bases 1‐formylpyrroldine (FPyr) and diethylcyclopropenone (DEC) as catalysts

  酰氯通常作为牺牲试剂来促进亲核取代（S N），以改善热力学驱动力并降低动力学障碍。但是，最便宜的酰氯光气（COCl 2）是剧毒气体。在这种背景下，发现氯甲酸苯酯（PCF）是S N固有的更安全的光气替代物使用醇形成C-Cl和C-Br键的类型。因此，事实证明，使用路易斯碱1-甲酰基吡咯烷酮（FPyr）和二乙基环丙烯酮（DEC）作为催化剂对于改变化学选择性有利于生成卤代烷烃至关重要。伯，仲和叔，苄基，烯丙基和脂族醇是合适的原料。可以耐受多种官能团，甚至包括酸不稳定的部分，例如叔丁基酯和乙缩醛。由于可以分离副产物苯酚，因此在技术规模上用廉价的光气回收到PCF是可行的。最终，一项全面的竞争研究表明，PCF的确优于光气和其他替代品。
